I have a carousel of large images. In order to optimize the amount of available memory I am trying to remove the offscreen sprites from the compositor and then invalidate them. However after i have done so using the r2d2_bitmaps command on port 8080 still shows the bitmaps in the graphics memory. What are the steps for removing a sprite and it’s corresponding bitmap from memory?
the relevant functions are below
'avalanche is called from a videoplayer, ads is json from the default getads interface
function avalanche(ads) as boolean
av = setup(ads)
if av.load("http://vmg-us.s3.amazonaws.com/demo/designlab/av-demo-app/source/rokucontent.json")
if av.events()
return true
end if
end if
